    • Disclosed is an aromatic amine derivative having a specific structure represented by the general formula (I) below. Also disclosed is an organic electroluminescent device wherein an organic thin film composed of one or more layers including at least a light-emitting layer is interposed between a cathode and an anode. Since at least one layer of the organic thin film contains the aromatic amine derivative by itself or as a component of a mixture, the organic electroluminescent device enables to obtain blue light emission with high color purity, while having long life and high luminous efficiency. Namely, the aromatic amine derivative enables to realize such an organic electroluminescent device. (I) [In the formula, A1-A6 respectively represent a hydrogen atom or the like; R1 and R2 respectively represent a hydrogen atom or the like; a represents an integer of 1-3. In this connection, at least one of A1-A6 represents a group represented by the following general formula (II) or (III): (II) (III) (wherein Ar1-Ar4 respectively represent a substituted or unsubstituted alkyl group having 1-50 carbon atoms or the like; Ar5 represents a divalent group obtained by removing one hydrogen atom from any of Ar1-Ar4; and b represents an integer of 1-3).]
    • 公开了具有下述通式(I)表示的具体结构的芳香族胺衍生物。 还公开了一种有机电致发光器件,其中由阴极和阳极之间插入至少包含发光层的一层或多层的有机薄膜。 由于有机薄膜的至少一层本身或作为混合物的成分含有芳香族胺衍生物,所以有机电致发光元件能够获得高纯度的蓝色发光,同时寿命长,发光效率高。 也就是说,芳族胺衍生物能够实现这种有机电致发光器件。 (I)[式中,A 1〜A 6分别表示氢原子等, R1和R2分别表示氢原子等; a表示1-3的整数。 在这方面,A1-A6中的至少一个表示由以下通式(II)或(III)表示的基团:(II)(III)(其中Ar1-Ar4分别表示取代或未取代的具有1- 50个碳原子等; Ar 5表示通过从Ar 1 -Ar 4中的任一个除去一个氢原子获得的二价基团; b表示1-3的整数。]
